In the drawings, A represents the stock of my improved shoulder-plane,which stock is made of cast metal, and provided with a flat bottomhavingvertical side shoulders. A. The side shoulders, as'wellas thebottom, are arranged with recesses for the inclined cuttingtool B,thenarrower upper part of which is provided with a slot, 1), whilethelower part has three cutting-edges, b, one at the lowerend and one ateach side, as customary in shoulderplanes. The slotted upper part of thecuttingtool B is clamped to interior cheeks, a c of the bottom part ofthe stock A by means of a tongue, (I, and a clamping-screw, d, thatpasses through a slot, d, of the tongue 0 and the slot 1) of thecutting-tool B, as shown clearly in Fig. 1.
